Hi i have some root cuttings from an apparently dormant passion flower vine that is a few years old. i cant find anywhere about how to go about starting these things off right, all cuttings seem to just be stem cuttings and seeds, i have like 6" roots with the tops cut off... so do i just pot them up and a new shoot will come up from where the top is cut off? i can include pictures, i just dont know how to start root cuttings... i dont know if to dip in root hormones or how far to plant under the soil. how lon they take if in a green house grow light condition until it warms up. thanks so much for your help guys.
